BrochureThe best solution for tensile and torsion testing. BV systems are available in a wide range
of loads, with torque capacities up to 200 Nm, the compact design requires minimal space
and offers a high level of rigidity and alignment. The torsional motor is coupled to every
linear actuator series we manufacture, from electromechanical actuators, EA series and all
UD, HUD and XUD series based on linear motors.
Equipped with STEP Lab's high-performance control electronics, the BV series provides
accurate test and control data for testing products and specimens from every industry.

The industries where they mainly find application are biomedical, automotive and aerospace,
but torsion testing are also common in the plastics industries, metals and fasteners.AXIAL TORSION SYSTEMS
